Why Explore Yellowstone by Bike?
Yellowstone National Park, a sprawling ecosystem of geothermal wonders, abundant wildlife, and dramatic landscapes, is best known for its geysers and grizzly bears. While most visitors experience its beauty from behind the wheel, one of the most rewarding—and environmentally friendly—ways to engage with Yellowstone is on two wheels. Cycling through Yellowstone offers a slower, more immersive experience. The scent of pine trees, the distant murmur of a hot spring, and the sight of a bison herd crossing the road become vivid moments rather than fleeting glimpses.
As both a passionate cyclist and a seasoned guide specializing in Yellowstone tours, I often recommend bike travel to visitors not just for its eco-friendly appeal, but for its capacity to create intimate, unforgettable connections with the landscape. In this article, I’ll guide you through some of the best bike routes in Yellowstone and share essential safety tips to help you prepare for your adventure.
Top Cycling Trails in Yellowstone
Though Yellowstone doesn’t boast an extensive network of dedicated bike paths like some other national parks, there are several roads and routes suitable for cyclists—each with its unique outlooks and experiences. Below are my top picks:
Grand Loop Road (Spring/Fall Access)
This is without a doubt the most iconic cycling route in the park. While normally used by motor vehicles in peak season, large portions of the Grand Loop become available to cyclists during the “shoulder seasons” (early spring and late fall) when roads are closed to vehicle traffic but open to non-motorized transport.
- Best Time to Ride: Mid-April to early May before park roads open to cars, or late October after they close.
- Highlights: Geysers around the Lower and Upper Geyser Basins, wildlife spotting around Hayden Valley, and scenic views near Yellowstone Lake.
- Recommended Section: The stretch between Mammoth Hot Springs and Norris Geyser Basin—less elevation change and less bison traffic.
Be aware that weather can still be unpredictable in spring and fall. Snow tires or fat bikes may be necessary depending on conditions.
Old Gardiner Road
Formerly a vehicle road and now an unpaved trail reserved for hiking and biking, the Old Gardiner Road provides a rigorous—but rewarding—ride. It runs between Mammoth Hot Springs and the park’s North Entrance near Gardiner, Montana.
- Distance: Approximately 5 miles (one way)
- Difficulty: Moderate to difficult due to gravel terrain and elevation gain
- Best For: Experienced cyclists and those comfortable riding on dirt and gravel.
What I love most about this route is the sense of isolation; very few people tread this path, making for a peaceful and personal ride.
Firehole Lake Drive (After Hours)
This 3-mile one-way loop road in the Lower Geyser Basin is typically used by cars during the day but becomes a quiet lane for cyclists in the early morning or evening.
- Distance: 3 miles, loop
- Terrain: Paved, relatively flat
- Notable Sights: Firehole Lake, Great Fountain Geyser, and steam vents that hiss gently just off the roadside
It’s one of my go-to recommendations for families or beginner cyclists. Keep an eye out for thermal areas that are close to the road—always stay on designated paths.
Lone Star Geyser Trail
This is one of the few trails in Yellowstone that allows bikes on a designated path. The trail follows an old service road alongside a serene river, ending at the Lone Star Geyser—a backcountry gem that erupts about every 3 hours.
- Distance: 4.8 miles (round trip)
- Surface: Gravel and dirt
- Ideal For: Cyclists looking for a wilderness experience with minimal climb
If you time it right, you might even catch an eruption with only a handful of people around. This trail exemplifies the quiet majesty Yellowstone has to offer beyond the usual crowds of Old Faithful.
Essential Safety Tips for Cyclists in Yellowstone
Yellowstone is wild—literally. Cycling here isn’t without its challenges and risks, and being prepared is pivotal to a safe and enjoyable experience.
Watch for Wildlife
One of the biggest thrills—and dangers—of biking in Yellowstone is wildlife. Bison, elk, and even bears frequently cross or walk along roadways.
- Always keep at least 25 yards (23 meters) from most wildlife, 100 yards (91 meters) from bears and wolves.
- Never attempt to pass bison or elk on the road. Wait until they move.
- Carry bear spray and know how to use it.
Share the Road
During peak months (late May through September), vehicle traffic can become dense—even overwhelming. Roads are narrow and shoulders are minimal.
- Use a bright rear reflector and wear high-visibility clothing.
- Ride single file and stay as far to the right as is safely possible.
- Pull over to allow faster vehicles to pass when safe.
If you’re not comfortable riding alongside vehicles, I strongly suggest visiting during the shoulder seasons when roads are mostly car-free.
Be Geothermal-Savvy
Many bike routes pass near thermal features like hot springs and geysers. While these are beautiful, they’re also dangerous.
- Stick to designated trails and boardwalks; crusty soil may not support you.
- Do not wade or swim in thermal waters unless specifically designated as safe.
- Always supervise children closely in these areas.
Come Prepared
Cell phone reception is unreliable, and services like water stations and restrooms can be sparse. Before setting out, ensure you have:
- Ample water and high-energy snacks
- Spare tubes and a flat repair kit
- Layers for changing weather conditions—temperatures can vary dramatically
- A physical map and knowledge of your route
When to Go: Best Times for Biking
The best times to cycle in Yellowstone depend heavily on your comfort level with traffic and weather. Spring and fall offer the advantage of low vehicle traffic—April and early May are particularly ideal for road cycling when the roads are open to bikes but closed to cars. Just be ready for snow and chilly mornings.
Summer offers stable weather and full access to the park’s facilities, but it also brings heavy traffic. If you plan to cycle in July or August, start early in the morning to beat both the heat and the cars.
Final Thoughts
Cycling through Yellowstone isn’t just a mode of transport—it’s a path to discovering the park at a rhythm that allows for both reflection and wonderment. You’ll hear the wind through the lodgepoles, feel the rise in temperature as you approach a geothermal vent, and smile at the crunch of gravel under your tires, all without the intrusive buzz of an engine.
Whether you’re a hardcore cyclist or a casual rider, Yellowstone offers something special. With thoughtful preparation and a mindful approach, your bike could be the key to unlocking the quiet, powerful essence of one of America’s most treasured landscapes.
